I was thinking of the walrus operator, various f-string changes, relenting on the "GIL removal must not cost performance" stance (although"covered" by other improvements), things like that.
I don't follow python closely so it may 100% be stuff that GvR endorsed too, or I'm mixing up the timelines. It just feels to me that python is changing much faster than it did in the 2.x days.

I think part of the reason Guido stepped down was that the BDFL structure created too much load on him dealing with actual and potential change, so its unsurprising that the rate of change increased when the governance structure changed to one that managed change without imposing the same load on a particular individual.
